one tablet keeps the hot flashes away.there is no doubt that soy is far better than pharmaceutical hormones as pharma's have a severe side effects as swelling parts in the body etc.. but there is also an open argument about side effects of soy,this one is none genetically modified which is good but we should also consider other natural herbs for woman hormone balancing and hot flashes other than isolated isoflavones derived from soy.
such herbs could be Black cohosh ( Cimicifuga racemosa ) , Angelica ( Angelica archangelica ),Angelica sinensis ( Dong Quai ), Anemarrhena asphodeloides ( Zhi Mu ) , Wild Yam Root ( Shan Yao ) , Cypripedium pubescens ( Lady’s slipper ),Asphodelus ramosus ( Tall asphodel ) or even Salvia officinalis ( Sage ) or Maca ( Lepidium meyenii ) which ever works for you :).even Astragalus membranaceus ( Huang Qi )has high content of natural isoflavones in it so i consider switching to it in the near future for its vast amount of other benefits in addition to the isolated isoflavones....you are welcome to rate & read my other reviews

Thank you Source Naturals and iHerb for carrying this convenient 1000mg Soy complex.
I trust I`ll notice improvement in my perimenopausal emotional rollercoaster in a few weeks- so far I`ve only taken them for about a week- but with these excellent ingredients I feel taken care of!
Update: I feel I owe an update to my fellow menopausal sisters because hot flashes etc are no joke: Unfortunately these did nothing particular for me, so sorry to say! I did fare a little better with the Transisions brand, and New Chapter's Estrotone, but not much. But of course- give it a try! We are the same, but all different! ;))
